According in the switching position of Fig. 1, drivening piece 6 is in zero-bit and do not have switch valve 4.1 to 4.5 to open.Therefore, gas outlet chamber 3 can be flowed to from chamber, gas access 1.2 without gas.All switch valves 4.1 to 4.5 seal in valve seal plate 5.
When drivening piece 6 is moved from zero-bit, so it causes the locking body 7 of the first switch valve 4.1 to be separated by with sealing plate 9 by the contact in the manipulation region 12 with the first switch valve 4.1 close to the first switch valve 4.1 there.Gas path on the direction in gas outlet chamber 3 and therefore on the direction of gas outlet 2 is so unlimited.This is shown in Figure 2.In example shown by Fig. 1 to 5, open the state of the first switch valve 4.1 corresponding to perfect combustion position, because can consider that pressure minimum loses in this arrangement.
When drivening piece 6 is mobile by continuation, so it causes it to be also separated by with sealing plate 9 by the contact in the manipulation region with second switch valve 4.2 close to second switch valve 4.2 there.In this moment, two switch valves 4.1 and 4.2 are opened (see Fig. 3).Changes in flow rate is preferably also unrealized, because the pressure loss realized by the nozzle opening of second switch valve 4.2 is greater than its situation in the first switch valve 4.1.
When drivening piece 6 is mobile by continuation with reference to figure 4, so drivening piece 6 loses the contact in the manipulation region 12 of itself and the first switch valve 4.1.This causes, and closes spring 11 and closes again the first switch valve 4.1, and the locking body 7 of the first switch valve 4.1 is sealed again on sealing plate 5.The changes in flow rate (see Fig. 4) of the reduction via second switch valve 4.2 is just realized in this moment.
When drivening piece 6 continues mobile until the 5th switch valve 4.5 and only also it opens (see Fig. 5), so in this position, realize minimum possible flow, because nozzle opening subsequently (it is opened by the 5th switch valve 4.5) preferably has minimum through flow cross section.In series the nozzle opening continued on the direction of gas outlet 2 by gas flow flows through preferably all has larger nozzle throat area, makes to realize further flow and reduces.Because all switch valves 4.1 to 4.5 are arranged parallel to each other, open or close to time lag, gas is forced arrangement by all openings 8 in spray nozzle board 9 until gas outlet 2.By this layout, do not cause upper punch (Ueberschwingen) or the undershoot (Unterschwingen) of flow in the moment of the corresponding switching process of switch valve 4.1 to 4.5.
In this gas valve unit, first gas flow through the switch valve that is arranged in parallel all the time and then flow through the nozzle opening of series connection.
The on off state of above-mentioned Fig. 1 to 5 advantageously can accurately copy.On off state can accurately copy, and even for flow minimum under maximum connection pressure, and does not cause upper punch or the undershoot of desired power stage.
In the switching process of switch valve, do not need lubricating grease, thus the movement of switching point can not be caused.
Mechanically the gas valve unit of switch can be operated by hand.Electronic equipment is optional, but can apply motor driver.
The rotating distance of about 320 ° is provided by arrangement according to the invention.Valve block can be constructed to ring or also be constructed to slide block.This gas valve unit can be used for any gas type, also can be used for liquid gas.
In addition, there is the variant of gas valve unit, the gas flow of relative base load change can be realized wherein in each switching stage.According to the design of open cross-section, the gas flow that relative base load improves all the time also can be shown.In addition, even if serrate profile also can be used for provided gas flow.
In addition, observe in the flowing direction at the structure selfsealings plate of some form of implementation breaker in middle valves of gas valve unit and also can design very simply, because the double punch of other gas distribution plate and spray nozzle board can be cancelled.
